Why is readAllStandardError() returning empty when called the second time? Can it only be read once?

stderrtxt1=run_command.readAllStandardError(); // has error content

stderrtxt2=run_command.readAllStandardError(); // returns empty

Hi! readAllStandardError reads all available data from the standard error channel. After that the input is empty until new data is written to the channel.
